redox::write!

( $ dst : expr , $ ( $ arg : tt ) * ) => (
$ dst . write_fmt ( format_args ! ( $ ( $ arg ) * ) ) )

Use the format! syntax to write data into a buffer.

This macro is typically used with a buffer of &mutWrite.

See std::fmt for more information on format syntax.

Examples

use std::io::Write;

let mut w = Vec::new();
write!(&mut w, "test").unwrap();
write!(&mut w, "formatted {}", "arguments").unwrap();

assert_eq!(w, b"testformatted arguments");
